Cannot find my form bean.

[Neil Hornbeck]

Hi all,
I am a first time struts user, and I am having trouble with the basics.  
Specifically, I am trying to start at index.jsp, and in IndexAction 
create a ListNamesForm bean, attach it to the session, and pass control 
via a 'success' mapping to listNames.jsp.  
        ListNamesForm lnf = new ListNamesForm();
        lnf.setAddressHeaders( ahd.getAddressHeaders() );
        HttpSession session = request.getSession();
        session.setAttribute( Constants.LIST_NAMES_FORM, lnf ); // constants = 
'listNamesForm'
        return ( mapping.findForward("success") );

I get the following error (truncated): 

javax.servlet.ServletException: Cannot find bean ListNamesForm in scope 
null 
at 
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContex
tImpl.java:459)
at 
_0002flistNames_0002ejsplistNames_jsp_16._jspService(_0002flistNames_000
2ejsplistNames_jsp_16.java:559) ..........(and so on)

I believe that web.xml, struts-config.xml are configured correctly.  Any 
ideas?

Thanks,
